G'day i've been recording cassettes on my mp3 player which stores them as wave files and then converting them to both mp3 and wma and they all work fine on xp media player. After being synched back onto the mp3 player I can find all the sub folders and files going thru my computer removable storage devices but on the mp3 player all I can find is the sub folders.Is this somethig to do with i.d.tags?I'm not much chop with these computer thingy's . Thanks in advance& thanks 4 the free stuff.
